Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,
A term Significant Figure refers to all the certain digits and one uncertain digit in a measurement.
All the digits are significant in this case. A zero between other digits is always significant, and all zeros after the decimal point are significant.
170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
Integers ending in 0 are ambiguous cases. The measurement could be accurate to the units digit and in that case all three digits are significant. But is could be accurate to the nearest ten, in which case, only the first two digits are significant.
A term Significant Figure refers to all the certain digits and one uncertain digit in a measurement.
One is certain and the other in uncertain.
the last number.
A significant figure in a measurement is a digit that carries meaning contributing to its precision. It includes all the certain digits plus the first uncertain digit. The number of significant figures indicates the precision of the measurement.
43.52 centimeters (cm) has four significant figures. The final figure in place four of '2' is the most uncertain. This is because the measurement device or calculation may have originally been 43.516 through 43.519 before rounding or due to instrumentation uncertainty.
The significant figures in a measurement include all digits measured exactly, plus one estimated digit.
Your measurement should include one estimated digit.
At most 1.
The number of significant figures in a measurement is determined by the precision of the measuring instrument. Include all certain digits plus one uncertain digit (estimated or interpolated). Nonzero digits, zeros between nonzero digits, and trailing zeros in numbers containing a decimal point are considered significant.
There are four significant figures in the measurement 77.09 meters. Each non-zero digit and any zeros between them are considered significant.

3 - assuming the trailing 0s are there for a reason.
